Description

向列型液晶組成物及使用其之液晶顯示元件 Nematic liquid crystal composition and liquid crystal display element using same

本發明係關於作為液晶顯示材料而有效用之介電常數各向異性(△ε)顯示負值的向列型液晶組成物及使用其之液晶顯示元件。 The present invention relates to a nematic liquid crystal composition exhibiting a negative value of dielectric anisotropy (??) which is effective as a liquid crystal display material, and a liquid crystal display element using the same.

液晶顯示元件係使用於以時鐘、電子計算機為首之家庭用各種電器、測定機器、汽車用面板、文字處理器、電子記事本、印表機、電腦、電視等。作為液晶顯示方式,其代表者中可舉出TN(扭曲向列)型、STN(超扭曲向列)型、DS(動態光散射)型、GH(賓主(guest host))型、IPS(平面內切換)型、OCB(光學補償雙折射)型、ECB(電壓控制雙折射)型、VA(垂直配向)型、CSH(彩色超垂面(color super-homeotropic))型、或FLC(強介電性液晶)等。又,作為驅動方式亦可舉出靜態驅動、多工(multiplex)驅動、單純矩陣方式、藉由TFT(薄膜電晶體)或TFD(薄膜二極體)等所驅動的主動矩陣(AM)方式。 The liquid crystal display element is used in various household appliances, measurement equipment, automobile panels, word processors, electronic notebooks, printers, computers, televisions, and the like, which are clocks and electronic computers. Examples of the liquid crystal display method include a TN (twisted nematic) type, an STN (super twisted nematic) type, a DS (dynamic light scattering) type, a GH (guest host) type, and an IPS (plane). Internal switching) type, OCB (optical compensation birefringence) type, ECB (voltage controlled birefringence) type, VA (vertical alignment) type, CSH (color super-homeotropic) type, or FLC (strong Electrical liquid crystal) and the like. Further, examples of the driving method include static driving, multiplex driving, a simple matrix method, and an active matrix (AM) method driven by a TFT (Thin Film Transistor) or a TFD (Thin Film Diode).

在該等顯示方式中,IPS型、ECB型、VA型、或CSH型等具有使用△ε顯示負值之液晶材料的特徵。在該等之中特別是藉由AM驅動的VA型顯示方式,係使用於被要求高速且廣角的顯示元件、例如電視等的用途。 Among these display modes, the IPS type, the ECB type, the VA type, or the CSH type or the like has a feature of using a liquid crystal material having a negative value of Δ ε. Among these, the VA type display system driven by AM is used for applications requiring high-speed and wide-angle display elements such as televisions.

對於使用於VA型等之顯示方式的向列型液晶組成物,係被要求有低電壓驅動、高速應答及寬廣的動作溫度範圍。即,被要求△ε為負且絕對值大、低黏度、高的向列相-各向同性液體相轉移溫度(Tni)。又,必須從折射 率各向異性(refractivity anisotropy,△n)與晶胞間隙(cell gap,d)之乘積△n×d的設定,將液晶材料的△n調節於符合晶胞間隙的適當範圍內。此外當應用液晶顯示元件於電視等時,由於重視高速應答性,故要求黏度(η)低的液晶材料。 A nematic liquid crystal composition used for a display mode such as a VA type is required to have a low voltage drive, a high speed response, and a wide operating temperature range. That is, a nematic phase-isotropic liquid phase transition temperature (T ni ) which is required to have a negative Δ ε and a large absolute value and a low viscosity and a high viscosity is required. Further, it is necessary to adjust the Δn of the liquid crystal material to an appropriate range in accordance with the cell gap from the setting of the product of the refractive index anisotropy (Δn) and the cell gap (d) Δn×d. Inside. Further, when a liquid crystal display element is applied to a television or the like, a liquid crystal material having a low viscosity (η) is required because of high speed responsiveness.

迄今,藉由各種研究△ε為負且其絕對值大的化合物而改善液晶組成物的特性。 Heretofore, the characteristics of the liquid crystal composition have been improved by various compounds in which Δε is negative and its absolute value is large.

作為△ε為負的液晶材料,已揭示使用具有如下之2,3-二氟伸苯基骨架之液晶化合物(A)及(B)(參照專利文獻1)的液晶組成物。 As a liquid crystal material having a negative Δ ε, a liquid crystal composition using liquid crystal compounds (A) and (B) having the following 2,3-difluorophenylene skeleton (see Patent Document 1) has been disclosed.

該液晶組成物雖使用液晶化合物(C)及(D)作為△ε幾乎為0的化合物,但該液晶組成物係未能達成在液晶電視等之要求高速應答的液晶組成物中實現足夠低的黏性。 In the liquid crystal composition, the liquid crystal compounds (C) and (D) are used as a compound having a Δ ε of almost 0. However, the liquid crystal composition is not sufficiently low in a liquid crystal composition which requires a high-speed response such as a liquid crystal television. Sticky.

另外,在專利文獻2或專利文獻3中,雖亦已揭示使用具有被氟取代之聯三苯(terphenyl)結構之化合物的液晶組成物,但為了對應於快速之影像或3D影像,從現在起更加要求高速應答性能。此外,雖有發展配合用於改善應答之窄幅晶胞(narrow cell)對應品而使用之液晶組成物的高△n化,但亦產生在低溫之溶解性的問題,故尋 求即使在用於高速應答的低黏性與低溫下亦兼顧穩定穩定地保持液晶相之溶解性的液晶組成物。 Further, in Patent Document 2 or Patent Document 3, a liquid crystal composition using a compound having a terphenyl structure substituted by fluorine has been disclosed, but in order to correspond to a fast image or a 3D image, from now on More demand for high-speed response performance. In addition, although there has been a problem of high Δn formation of a liquid crystal composition used for improving a response of a narrow cell counterpart, it also causes a problem of solubility at a low temperature, so Even in the low viscosity and low temperature for high-speed response, a liquid crystal composition which stably and stably maintains the solubility of the liquid crystal phase is obtained.
